1. A method of wireless communication performed by an aerial user equipment (UE), comprising:
measuring a first offset associated with a downlink frame based at least in part on a time when a downlink signal is received from a terrestrial base station;
determining a second offset corresponding to a starting time for the downlink frame at the terrestrial base station; and
transmitting an uplink message in an uplink frame using a timing advance that is based at least in part on a value of the first offset and a value of the second offset relative to a starting time associated with a global navigation satellite system (GNSS) frame duration.
